tested as previously required of the existing pipe, and that all activities be performed in accordance with applicable requirements of 49 CFR Part 195. The revised Order also stipulated that OPS would review and approve Calnev’s hydrostatic testing and inspection program, that OPS would monitor the test, and that the pipeline could not be returned to service until OPS had determined that all required actions had been successfully completed.

By letter of June 6, 1989, Calnev requested relief from the requirements of the Order because it discovered that a bend in the pipe made it impractical to tie into the new pipe 10 feet north of the Highland Avenue casing, the location required by the amended Order. As there was no apparent damage to the pipe at that location and because the line would be hydrostatically tested before returning it to service, on June 6, 1989, the OPS again amended the Order to allow the tie-in to be made at a location determined acceptable by Calnev and concurred with by a representative of the OPS so long as the tie-in was made between the point 10 feet north of the Highland Avenue casing and a point about 35 to 40 feet north of the casing.

About 600 feet of the pipeline through the area of the previous derailment was removed and replaced. The pipeline was refilled with product on June 9, 1989. More than 9,400 barrels of product were required to refill the pipeline. A mile of pipeline of the size installed will hold 917.69 barrels of product, based on information provided by Calnev.

Train Derailment.—Five locomotive units and the entire consist of 69 hoppers cars were completely destroyed as a result of the derailment; the rear-end locomotive was extensively damaged. About 680 feet of track were destroyed by the derailing locomotive units and cars.

Following the derailment, a building inspector from the City of San Bernardino Department of Building and Safety inspected the houses that incurred damages as a result of the derailment. The inspector’s assessment of damages is listed in Appendix F. The inspector recommended that dwellings at 2314 Duffy Street through 2382 Duffy Street be demolished immediately (figure 11).
